CREDO-DYE-N

The Credo Dye laser is a unique narrow bandwidth tunable laser designed for high repetition rate excitation. It features an ultra-low-threshold oscillator for high conversion efficiency at low pulse energies.
Special dye cells combine rapid flow of the dye solution with high pump power capabilities. Repetition rates up to 150 kHz are possible. Average pump powers of up to 200 W can be used.
